9. Chronic Dryness and Persistent Eyelid Itching Chronic dry eye is more than just a minor discomfort; if left untreated, it can cause fluctuating vision, a constant foreign-body sensation, and even paradoxical tearing. Over time, severe dryness can damage corneal nerves and impair the eye’s ability to heal, potentially leading to permanent scarring. Similarly, persistent itching of the eyelids may stem from chronic allergies, bacterial infections, or an overgrowth of Demodex mites in the hair follicles. Only a professional examination can determine the exact cause and provide a treatment plan to protect the long-term health of the ocular surface.
